Exit but do not close:This is an Android optimized for Linux. When the Android application exits, it does not clean up the memory it consumes, and the Linux kernel process continues to exist, so-called "quit without shutting down". This allows the user to get a response at the first time when invoking the program.App switching to the background is paused, completely CPU-and power-intensive, leaving only the

is switched on, activity A is destroyed and activity A is automatically created after the screen switch, so onsaveinstancestate is bound to be executed. In summary, Onsaveinstancestate's invocation follows an important principle that when the system destroys your activity "without your permission", then Onsaveinstancestate is called by the system, which is the responsibility of the

. We do not need to reinitialize the component in a series of callback methods that revert to the resumed state. Resume ActivityWhen the user resumes activity from the paused state, the system calls the Onresume () method.Note that every time the system calls this method, the activity is in the foreground, including the first time it is created. Therefore, you should implement Onresume () to initialize

flash or SD card boot program, the boot program is generally ubootUboot will be finished initializing some devices, the very important part here is NAND flash, in order to load the Linux kernel into the memory and execute.The kernel that is loaded may be the kernel in the boot partition, depending on the situation. It is also possible that the kernel in the recovery partition.After the kernel runs, it will first mount the RAMDisk to the "/" root fold

How to completely back up the system partitions and data partitions on the android system, androiddata Android system backup may be used in many cases, the following python script, can be used to back up the entire data Partition: All the datapartition files and directories

Java code and interpreted and executed in Dalvik VM. In the Android operating system, each Instance of each Dalvik VM corresponds to a process in the Linux kernel. You can use the adb shell tool to view the current process in the system. As shown in, the list of processes in the kernel after Android2.3.3 is started Android
